Prediction markets are fascinating to me. Of course they are not perfect, as demonstrated by this post, and also by the spreads of certain "fan favorite" sports teams that people throw money at irrationally. I still think that on average (just like prices in any other decentralized markets), the prediction prices are better than any known centralized system, and with a robust implementation, could be used for important planning.
